METALLIC DOOR-SILL.

SPECIPICA'IION formng part of Letters Patent No. 324,732, datecl Aug11st 13, 1885:

Applieatieu f.le11 June 18, 1885.

T0 aZZ w7wm ii mcny concern:

Be 1't knewn t11at I, CHARLES O. SOIIREIBER, a resident of Cneinnati, in the county of Hamilton and State of Ohio, have invented eertain new and usefnl Improvennents in Metallic Deer-Sills, of which the following is a spec fiealion.

My invention relates te a metallic doorsill.

M is very desirable te e1nploy f0r outside deers metallic deor-sills beeause of their durability. Cast-iron doorsills have been emp'oycd f01 this purpese; leut, owing to their linblity te fraetme, they ai"e n0t desirable. I have discevered that by making a metallic sill of 1elled i1011 of semi-arch form, having wings to support 1110 sill, it ean be conveniently and safely used. 'Ihe wings also may be readily inereased 01 lessenecl in their vertical l1eight, se as te fit the spaee beneath the door te form a Weather-joinb, all of whieh Will be full y seb forth in the cleseription of the aecompanying drawings, making a part of this speeification, in whieh Fignre 1 is a top plan view 0'1ny improven1ent; Fig. 2, a section 011 line 00 00, Fig. 1.

This deor-sill is made of rolled iron, with the center eorrugated, having ribs a and (lepressions b, of any clesired form, s0 as te ferm 11 reugl1ened surfaee te prevenb slpping. c 0 represent tl1e wings whieh form the semi-arch spaee A between the wings 111d below the centra] perbion of the plate.

Tl1e device may be made in two ways-first, by rolling tl1e eorrngations from a piece of (N0 model.)

flat 01 bar i1011, and then passing the same through afianging-maehine to turn down tl1e --wngs c e; 01 the rolls may be turned s0 as te 1011 the pieee direct.

As the device is made of rellecl iren tl1e wings may be rea(lily flattened 01 reclneed in vertical height by hammering 01 eonnpression appliecl l30 t11eir shenlders, s0 as te lessen the vertieal height of the sil1 ancl fib it te any clesirecl spaee in the door.

Tl1e device is kept in position by means of spikes er screws driven tl1rougl1 holes d; 01 wood-serews may be employed for this pur pose.

e represents small el1annels er groeves ent: aeress t he eorrugatons a b, se as te drainthe water out of the hellows 01 depressons.

This device ean be easily made of the desirecl length ancl readily applied te its pesi tien.

Having describecl 1ny invention, what I elai 111 as new is- A rellecl-iron cl0or-sill having its 1evel per bien grooved, and formecl Witl1 tl1e flexible wings c e, eapalele of being bent as deseribecl, te increase 01 deerease the height of the sill, substantially as and for the pnrpose set forth.

In testimony whereof I have hereunto set my hand.

CHARLES O. SCIIREIBER.
